F3SJ-A2120P30

Light curtains, or more commonly known as safety light curtains, are a type of electro-sensitive protective devices that are commonly used in machines’ safety systems. They are used to monitor particular area and detect unauthorized access to the protected area. F3SJ-A2120P30 is one of the most popular light curtain models which is widely used in applications of safeguarding personnel and detecting foreign objects. It is the third generation of F3SJ light curtain with improved performance, and is ideal for use in production line, automatic doors and emergent stop in machines.

F3SJ-A2120P30 light curtain is an alignment-free, safety-rated light curtain. It does not require any set up during installation and therefore is easier to use. It is suitable for small and medium-sized dangerous areas monitoring, and can detect objects that are not allowed to enter the protected area. The light curtain is a pair of two paralleled cables that emit and receive light beams, which is invisible to the human eye. If the beams are blocked, the system will detect it immediately and activate the emergency stop. This prevents any potential danger to personnel, and ensure the safety of the work environment.

The specific principle that the F3SJ-A2120P30 light curtain works is that the F3SJ-A2120P30 light curtain has one transmitting light curtains and one receiving light curtain. Both curtains are parallel to each other and are connected to safety controller. During the normal running state of the machine, the light is sent from the transmitting light curtain to the receiver continuously, and the receiver light curtain would detect the light beams. If an object enters between the two light curtains, the detection area will be blocked, the interruption signal will be detected, and the safety controller will then activate the emergent stop.

The advantage of F3SJ-A2120P30 light curtain over other models is that it has a higher level of resolution and safety functions. It can detect foreign objects as small as 4 mm and protect an area of up to 1.2 meters, which is higher than the conventional safety light curtains. Besides, there are additional built-in functions such as muting, blanking and dual safety input for confirmation, which significantly enhances the safety of workers. This product is also certified by various safety regulations, such as having CE and UL approval.

In conclusion, F3SJ-A2120P30 light curtain is widely used in machine safety systems. It is a powerful and reliable tool for safeguarding personnel and protecting machines from unauthorized access. The product is easy to install, reliable, and is certified by safety regulations.
